被动语态可以不带be动词么?
请详解一下这道题·········
Experts think that we need to eat meat because it contains vitamins and minerals _____ in vegetables.
A.not finding B.not to find C.not found D.which is not found
答案解析是；vitamins and minerals 与 find 之间是被动关系,所以应使用过去分词；B项表示将来的动作；D项英使用which are not found
C项里面没有be动词呀?不是说被动语态都要有被动词么?
